How to Use DEXs: Uniswap, PancakeSwap, and More (2025 Guide)
Table of Contents
What Are DEXs?
Decentralized exchanges (DEXs) are blockchain-based platforms that allow users to trade cryptocurrencies directly, peer-to-peer, without a central authority. DEXs use smart contracts to automate trades, ensuring privacy, autonomy, and global access. Popular DEXs include Uniswap (Ethereum), PancakeSwap (BSC), and SushiSwap (multi-chain).
- Privacy: No KYC required for most DEXs.
- Control: You hold your own funds; no custodial risk.
- Transparency: All trades are on-chain and auditable.
- Global Access: Anyone with a wallet and internet can use DEXs.
Types of DEXs
| Type | Description | Examples |
|---|---|---|
| AMM (Automated Market Maker) | Uses liquidity pools and algorithms to set prices. | Uniswap, PancakeSwap, SushiSwap |
| Order Book DEX | Matches buyers and sellers via on-chain or off-chain order books. | dYdX, Loopring |
| Aggregator | Finds best prices across multiple DEXs. | 1inch, Matcha |
| Hybrid | Combines centralized and decentralized features. | DeversiFi |
How to Trade on DEXs: Step-by-Step
- Install a crypto wallet (e.g., MetaMask, Trust Wallet) and fund it with crypto.
- Connect your wallet to the DEX (e.g., Uniswap, PancakeSwap).
- Select the token pair you want to trade.
- Enter the amount and review slippage, fees, and price impact.
- Confirm the transaction in your wallet and wait for blockchain confirmation.
- Check your wallet for the new token balance.
Always verify token contract addresses via official sources to avoid scams.
Providing Liquidity & Earning
- Deposit tokens into liquidity pools to earn a share of trading fees.
- Yield farming: Earn extra rewards (e.g., CAKE, SUSHI) for providing liquidity.
- Be aware of impermanent loss ā the risk of holding volatile assets in pools.
- Use stablecoin pairs (e.g., USDC/DAI) to reduce impermanent loss.
- Withdraw liquidity at any time, but check for potential penalties or fees.

Frequently Asked Questions
What are the main risks of using DEXs?
Risks include smart contract bugs, impermanent loss, slippage, and scams with fake tokens. Always research and follow best practices.
How do DEXs differ from centralized exchanges?
DEXs are non-custodial, peer-to-peer, and require no KYC. You control your funds, but must manage your own security and transactions.
What is slippage and how can I minimize it?
Slippage is the difference between expected and actual trade price. Trade high-liquidity pairs, use limit orders, and adjust slippage tolerance.
Why do gas fees vary so much?
